Question Is necessary to buy a thermic past for the 2700x/3800x processors?

[Tesla200]

I'm deciding to buy one of those processors but don't know if the processors came whit their own thermic past, I know those processors came with coolers but don't know if the thermic past is included.
Is necessary the thermic past?
Is the thermic past included?

I dont think its included, but to be sure, ask the one selling it

They have thermal paste pre-spread on the cooler. It isn't necessary to buy your own if you are purchasing a new unit.
